|
| 1 - CLASS |
Copies one or more existing classes to form one or more new
classes. If you copy a class to the same library, the new
class must have a different name. The COPY CLASS transaction
preserves all class attributes and inserts element generations
that belong to each input class. The elements to be inserted
into the new class must already exist in the target library.
Format:
COPY CLASS old-class-expression new-class-name "remark"
1.1 - Command Parameters
old-class-expression
Specifies one or more existing classes to be copied. If you
specify more than one class to be copied, you must use a
wildcard character for the new class name. An old class
expression can be a class name, a wildcard expression, or a
list of these separated by commas.
new-class-name
Specifies the name for the new class. The name cannot be the
same as any existing class name in the target library. Wildcards
are allowed. If you specify more than one class with COPY CLASS,
you must use a wildcard character for the new class name.
remark
Specifies a character string for the creation remark of the new
class to be logged in the history file with this command. The
remark is enclosed in quotation marks. If no remark was entered,
then the remark from the old class is used for the creation
remark of the new class, but a null remark ("") is logged in
the history file.
1.2 - Description
The COPY CLASS command uses an existing library class to copy
and create a new class in the same library or in another library.
The original class is left unchanged. The class attributes are
copied in full and an identical set of element generations are
inserted into the new class. The elements to be inserted into
the new class must already exist in the target library.
CMS must be able to create one new class for each old class.
When you use wildcards, or a comma list in the input class
specification you must specify a wildcard ("*") as the output
class specification.
1.3 - Qualifiers
1. 3.1 - /CONFIRM
Controls whether CMS prompts you for confirmation before each
transaction.
When you specify /CONFIRM and run CMS in interactive mode, CMS
prompts you for confirmation. If you type YES, ALL, TRUE, or 1,
CMS executes the transaction. If you type NO, QUIT, FALSE, 0,
or press RETURN or CTRL/Z, no action is performed. If you type
any other character, CMS continues to prompt until you type an
acceptable response.
CMS does not prompt for confirmation in batch mode.
1. 3.2 - /LIBRARY[=directory-specification]
Identifies a valid CMS library that is the location of the class
specified by the old-class-expression parameter. When you
specify an alternative library, the new-class-name parameter is
optional. If you do not specify a value for /LIBRARY, the current
CMS library is used.
1. 3.3 - /LOG (D)
Controls whether CMS displays success and informational messages
on the default output device. By default, if the command executes
successfully, CMS displays a success message. If you specify
/NOLOG, success and informational messages are suppressed. Any
warning, error, or fatal error messages are displayed regardless
of whether /LOG or /NOLOG is specified.
1. 3.4 - /OCCLUDE[=option,...]
Controls whether CMS selects the first instance of the specified
object, or all instances of the specified object in the library
search list. The options field contains one or more keywords
associated with the name of the object. The options field can
contain the following keywords:
ALL--equivalent to CLASS
CLASS (D)
NOCLASS
NONE--equivalent to CLASS
You can specify either ALL, NONE, or the [NO]CLASS keyword.
By default, CMS performs occlusion for all objects; that is, CMS
selects only the first occurrence of a specified object.
1.4 - Example
CMS> COPY CLASS INIT_CLASS INITX_CLASS "experimental version"
%CMS-S-COPIED, class DISKX:[PROJECT.CMSLIB]INIT_CLASS copied
to INITX_CLASS
This command creates a new class named INITX_CLASS in the same
library as the old class.
| 2 - ELEMENT |
Copies one or more existing elements to form one or more new
elements. If you copy an element to the same library, the new
element must have a different name. The COPY ELEMENT transaction
preserves all element attributes, data, and generation/variant
information.
Format:
COPY ELEMENT old-element-expression new-element-name "remark"
2.1 - Command Parameters
old-element-expression
Specifies one or more existing elements to be copied. If you
specify more than one element to be copied, you must use a
wildcard character for the new element name. An old element
expression can be an element name, a group name, a wildcard
expression, or a list of these separated by commas.
new-element-name
Specifies the name for the new element. The name cannot be the
same as any existing element name in the target library. The file
name component cannot be 00CMS because this name is reserved for
CMS. Wildcards are allowed. If you specify more than one element
with COPY ELEMENT, you must use a wildcard character for the new
element name.
remark
Specifies a character string for the creation remark of the new
element to be logged in the history file with this command. The
remark is enclosed in quotation marks. If no remark was entered,
then the remark from the old element is used for the creation
remark of the new element, but a null remark ("") is logged in
the history file.
2.2 - Description
The COPY ELEMENT command uses an existing library element to
copy and create a new element in the same library or in another
library. The original element is left unchanged. The generation
history, file characteristics, and element attributes are copied
in full.
If the existing element has the reference copy attribute enabled
(that is, if it was created or modified with /REFERENCE_COPY),
the reference copy attribute is also enabled for the new element
(assuming the reference copy attribute is established for the
library).
If the existing element is reserved when you issue COPY ELEMENT,
CMS informs you of the condition, then proceeds with the
transaction. The new element is not reserved, regardless of
whether the original element is reserved at the time of the copy
transaction.
If a generation of the element is marked pending review, CMS
informs you of the condition, then asks whether you want to
proceed. If you type YES, CMS records the transaction as an
unusual occurrence and proceeds with the command. The new element
is not marked as pending review, regardless of whether the
original element is marked at the time of the copy. If you type NO
or press RETURN, no further action is taken.
CMS must be able to create one new element for each old element.
When you use wildcards, a group name, or a comma list in the
input element specification, CMS builds a list of elements to
be copied. CMS uses this list as the point of reference during the
copy transactions. If the output element specification does not
allow CMS to create a new element for each element in the input
list, the results may not be what you intend. For example, the
following combination of wildcard expressions produces only one
new element:
input element specification - *.FOR
output element specification - NDATA.*
The first element that matches the input specification (*.FOR)
produces one new element named NDATA.FOR. Each successive element
that matches the input specification generates an error message
because CMS can create only one unique element name from the given
combination of wildcard expressions.

search list. The options field contains one or more keywords
associated with the name of the object. The options field can
contain the following keywords:
ALL--equivalent to (ELEMENT, GROUP)
ELEMENT (D)
NOELEMENT
GROUP (D)
NOGROUP
NONE--equivalent to (NOELEMENT, NOGROUP)
You can specify either ALL or NONE, or any combination of the
[NO]ELEMENT and [NO]GROUP keywords.
By default, CMS performs occlusion for all objects; that is, CMS
selects only the first occurrence of a specified object.

This example creates a new directory for a new library,
and then copies all of the elements from the library
[PROJECT.CMSLIB] into the new library [RELEASE.CMSLIB].
Because the new elements are being created in a separate
library, CMS can create new elements with the same names as
the old elements; thus, a null string may be entered for the
second parameter (for the new element name). In this case,
CMS supplies the value *.*.
The SHOW HISTORY command that is executed after the copy
transaction indicates that the library history contains only
records of transactions performed on the new library (CREATE
LIBRARY and COPY transactions). The SHOW GENERATION/DESCENDANTS
command shows the generation history for one of the elements.
The COPY ELEMENT transaction preserves the generation history
for each element; thus, the record of replacement transactions
(also the CREATE ELEMENT transaction that produced generation 1
of the element) is maintained from the old element to the new.
| 3 - GROUP |
Copies one or more existing groups to form one or more new
groups. If you copy a group to the same library, the new
group must have a different name. The COPY GROUP transaction
preserves all group attributes and inserts elements and groups
that belong to each input group. The elements to be inserted
into the new group must already exist in the target library.
Format:
COPY GROUP old-group-expression new-group-name "remark"
3.1 - Command Parameters
old-group-expression
Specifies one or more existing groups to be copied. If you
specify more than one group to be copied, you must use a
wildcard character for the new group name. An old group
expression can be a group name, a wildcard expression, or a
list of these separated by commas.
new-group-name
Specifies the name for the new group. The name cannot be the
same as any existing group name in the target library. Wildcards
are allowed. If you specify more than one group with COPY GROUP,
you must use a wildcard character for the new group name.
remark
Specifies a character string for the creation remark of the new
group to be logged in the history file with this command. The
remark is enclosed in quotation marks. If no remark was entered,
then the remark from the old group is used for the creation
remark of the new group, but a null remark ("") is logged in
the history file.
3.2 - Description
The COPY GROUP command uses an existing library group to copy
and create a new group in the same library or in another library.
The original group is left unchanged. The group attributes are
copied in full and an identical set of elements and groups are
inserted into the new group. The elements to be inserted into
the new group must already exist in the target library.
CMS must be able to create one new group for each old group.
When you use wildcards, or a comma list in the input group
specification you must specify a wildcard ("*") as the output
group specification.
3.3 - Qualifiers
3. 3.1 - /CONFIRM
Controls whether CMS prompts you for confirmation before each
transaction.
When you specify /CONFIRM and run CMS in interactive mode, CMS
prompts you for confirmation. If you type YES, ALL, TRUE, or 1,
CMS executes the transaction. If you type NO, QUIT, FALSE, 0,
or press RETURN or CTRL/Z, no action is performed. If you type
any other character, CMS continues to prompt until you type an
acceptable response.
CMS does not prompt for confirmation in batch mode.
3. 3.2 - /LIBRARY[=directory-specification]
Identifies a valid CMS library that is the location of the group
specified by the old-group-expression parameter. When you
specify an alternative library, the new-group-name parameter is
optional. If you do not specify a value for /LIBRARY, the current
CMS library is used.
3. 3.3 - /LOG (D)
Controls whether CMS displays success and informational messages
on the default output device. By default, if the command executes
successfully, CMS displays a success message. If you specify
/NOLOG, success and informational messages are suppressed. Any
warning, error, or fatal error messages are displayed regardless
of whether /LOG or /NOLOG is specified.
3. 3.4 - /OCCLUDE[=option,...]
Controls whether CMS selects the first instance of the specified
object, or all instances of the specified object in the library
search list. The options field contains one or more keywords
associated with the name of the object. The options field can
contain the following keywords:
ALL--equivalent to GROUP
GROUP (D)
NOGROUP
NONE--equivalent to GROUP
You can specify either ALL, NONE, or the [NO]GROUP keyword.
By default, CMS performs occlusion for all objects; that is, CMS
selects only the first occurrence of a specified object.
3.4 - Example
CMS> COPY GROUP INIT_GROUP INITX_GROUP "experimental version"
%CMS-S-COPIED, class DISKX:[PROJECT.CMSLIB]INIT_GROUP copied
to INITX_GROUP
This command creates a new group named INITX_GROUP in the same
library as the old group.
